Stephen,
There are ways to do it. But some of them consists complex grid math. Take the easy way I would say if your table is RowBuffered or have a flag field. With rowbuffering you would do something like :

this.setall("Enabled", recno()<0,"Textbox")

If you prefer the math way then you could furnish this code to your taste :

*beforerowcolchange
LPARAMETERS nColIndex
llChangingRow = .f.
WITH this
  oColumn = .columns(.FindColumn(nColIndex))
  IF lastkey() = 145 && Adding new rec - personal choice to trigger add (Ctrl+dnarrow)
    .nLastValidRec = .nCurrec   && Both custom grid properties
  ENDIF
  thisform.LockScreen = .lInGrid && Related with higlight - custom property
  IF mdown()
    lnBottom		= .top+.headerheight+.relativerow * .rowheight
    lnTop			= lnBottom - this.rowheight
    lnMouseRowPos	= mrow(wontop(),3)
    lnMouseColPos	= mcol(wontop(),3)
    llChangingRow	= !(between(lnMouseRowPos,lnTop, lnBottom) ;
      and between(lnMouseColPos,.left,.left+.width))
  ELSE
    llChangingRow	= inlist(lastkey(),24,5,18,3,145,148)
  ENDIF

  IF llChangingRow
    *....  && User attempted to change row
    * if cannot let to go
    nodefault
    *else
    *....
    *endif
  ELSE
    *...
  ENDIF
ENDWITH

* Custom findcolumn method
LPARAMETERS nColIndex
LOCAL ix
WITH this
  FOR ix = 1 to .columncount
    IF .columns(ix).ColumnOrder = nColIndex
      RETURN ix
    ENDIF
  ENDFOR
ENDWITH
